"The worst reproach that Engels could make against the first English Marxists was that they were applying Marxism in a sectarian spirit. What would he have said, had he lived to see it, about a school of Marxists who after succeeding in capturing the state power proceeded to make a state religion of Marxism, a religion whose articles of faith and their interpretation are watched over by the government, a religion, the criticism of which, nay, the slightest deviation from which, is sternly punished by the State; a Marxism ruling by the methods of the Spanish Inquisition, propagated with fire and sword, practicing a theatrical ritual, as illustrated by the embalmed body of Lenin: a Marxism reduced to the status not only of a state religion but of a medieval or oriental faith? Such a Marxism may indeed be called a doctrinaire fanaticism."

“I expect that soon the failure of the attempts to transform Russia into a Socialist community by methods of dictatorship will become apparent to all. The failure of the Communist experiment in Russia, however, does not mean the downfall of the Bolshevik regime. The two things are not necessarily linked together. Nay, they are mutually exclusive. The same backwardness that makes Socialism in Russia at the present time impossible favors the strengthening of despotism once it has taken root.”

“Dictators may torture or kill us, but they shall not succeed in demoralizing the soul of our movement, in bringing it to a state where for the sake of saving its life it is willing to renounce its ideal. Our cause will conquer in spite of everything, for in economic life as well as in politics the highest ability to accomplish and to advance things belongs to communities and organizations of free men working in free cooperation. These free communities will far outstrip every collective body, every organization that is built on compulsion and that can be maintained only by brute force; and ultimately the communities based on oppression will perish.”

“Marxism and Bolshevism: Democracy and Dictatorship”

“He who thinks that lasting peace can be brought about by means of war, “the last war,” is wrong. Equally wrong are those who imagine that the working class can be assured prosperity and freedom by organizing economic life an a militaristic basis. No less erroneous is it to strive for a dictatorship for the purpose of crushing the enemy and establishing the proletariat in a privileged position in the state and Society while reducing the rest of the population to the position of pariahs as a means of establishing ultimately socialist equality for all. But most objectionable of all would it be to attempt to build a regime of humanity upon the basis of brutality.”

“When brought to the proletariat from the capitalist class, science is invariably adapted to suit capitalist interests. What the proletariat needs is a scientific understanding of its own position in society. That kind of science a worker cannot obtain in the officially and socially approved manner. The proletarian himself must develop his own theory. For this reason he must be completely self-taught.”

“According to the laws of social development established by Marx, a backward agricultural country cannot show the way to Socialism to other countries. Its failure in this respect is foreordained. It is merely a question of when and how this failure will finally manifest itself. Until now the Bolsheviki have been skillful in disguising their failure under the mask of promises of a glorious future. The last such promise was the Five-Year plan. But the Bolshevist state economy has been in existence now more than fifteen years. For more than ten years the USSR has been enjoying complete peace. And yet, contrary to all promises, things under the Bolshevist state economy have been getting worse every year, , and the day is not far distant when even the most credulous will become convinced that the Bolshevist way leads not upward, toward Socialism, but downward, to open ruin or slow disintegration.”
